That's according to Square Enix producer Shinji Hashimoto, who explained at Thailand's Comic-Con (via Mognet Central) that from the start, the entire process had been about the two companies helping each other out.

"Back in 2001, Square Enix had financial problems and Sony bought our stocks," he explained. "Now, the situation is reversed. Since then, we have had good support from our customers for our products, so Square Enix is back on its legs.

“But Sony has declined. The presidents of both companies had negotiation and resulted as everyone knew. We did not have argument. Since Sony once helped us, it was time we helped Sony back.”
